 Revision history for CG_Labs
 
 
+v2020.0 2020-08-25
+==================
+
+New features
+------------
+
+* For those with GPUs (or GPU drivers) which do not support OpenGL 4.1: check
+  out the `OpenGL_3.3 branch
+  <https://github.com/LUGGPublic/CG_Labs/tree/OpenGL_3.3>`_.
+* In any of the assignments, you can use *F11* to toggle between windowed and
+  fullscreen mode.
+* In the first assignment for EDAF80, textures for all planets (plus the Sun and
+  the Moon) are loaded by default, and constants for their orbit and spin
+  configurations are provided.
+* In the second assignment for EDAF80, a set of control points is now provided;
+  there are represented as small spheres in the 3-D view (once
+  `parametric_shapes::createSphere()` has been implemented).
+* When using the `node::render()` function and GL_KHR_debug is available, all
+  OpenGL calls will be placed within a `glPushDebugGroup()` and
+  `glPopDebugGroup()` pair using the node’s name, to improve debugging.
+
+Improvements
+------------
+
+* All assignments have received several improvements and tweaks, for example
+  EDAF80’s third assignment will create and render two spheres by default (one
+  for the skybox, and one on which Phong shading and normal mapping will be
+  performed).
+* The API of all `parametric_shapes` methods has been modified to be more
+  consistent and clearer.
+* `displayTexture()` no longer takes a camera as input to retrieve the near and
+  far parameters used to linearise values read from depth textures, but now
+  take those directly as argument instead.
+* The shader for celestial bodies’ rings no longer uses an opacity texture but
+  instead uses the alpha channel of the diffuse texture.
+* Removed unused code and replaced other with standard types.
+* The vertical inversion of textures is now performed by STB.
+* Re-use functionalities from GLAD
+* The `set_uniforms` parameter of several methods of `Node`, has been made
+  optional.
+* Switch Travis to use Ubuntu Focal and add macOS to the tested environment.
+* A lot of improvements on the CMake configuration files to modernise them,
+  make them clearer, remove unnecessary operations, display additional
+  information when dependencies fail to download or build, etc.
+* Reorganise CHANGES.rst and add release date for v2019.1
+
+Fixes

+
+* Do not make helper functions load relative to specific directory
+* Do not use `abs()` on floating point numbers
+* Trigger a copy of the DLLs for all targets
